RE: gnubg: new features

[Ian Shaw]

Hi Isaac and Aaron, 

Thank you! This is a really good feature that I've been wanting for a long 
time. I hope there will be a Windows executable at some point. 

The Score map is a step above what Snowie used to have; buttons for $, DMP, GS, 
GG.

As for the layout, I think for the Move comparison, the natural shape of the 
table means that the options will fit better when presented below the table, as 
you have on page 2. Then it makes sense for the Doubling window to follow the 
same layout. I have a small preference for 'Vertical 1' over 'Vertical 2'.

I would eliminate the options for 'True Score' and 'Away Score'. Anybody 
serious enough to study in this detail is going to be thinking in 'Away' terms, 
so just use that. 

The Jacoby could be a simple on/off tick box to save room. 

On the cube action table, it's not clear to me what the use of upper and lower 
case letters mean (d/T D/T) etc. In any case, they seem to add not much more 
than the colour code already gives you. How about replacing them with the 
equity in millipoints? E.g. a D/T might be 985, a D/P a 1023. This would be 
similar to the 'show equities' option in the Temperature Map feature.

The colour coding is a great idea. Perhaps Too Good should be another colour to 
distinguish it from the normal No Double; Gold for Too Good/Pass and Purple for 
Too Good/Pass.

It would be useful for the actual score of the match being analysed to be 
highlighted in the grid, perhaps with a bold black border. 

In the moves list, it would probably be useful to add a symbol such as § if the 
correct score based-move differs from money play. 

Will this feature be something that's included as an option in the 'Analyse 
match' settings? Obviously, it would extend the analysis time by a lot to 
analyse all moves at all scores, so an option to select just the comparison of 
the current match score vs money might be good. 

I hope you find some of these suggestions useful.

Cheers,
Ian Shaw

Subject: gnubg: new features

We are happy to present three new features of gnubg on which we have been 
working quite a lot. We hope you will enjoy them.

We both find ourselves often wondering how much of the GNUBG eval is due to the 
score. Instead of repeatedly copy-pasting positions and editing them at various 
scores, we thought we could automate the process. So we coded new buttons for 
gnubg:
- Feature 1: the Money Eval button for cube decisions, which quickly provides 
an eval for the current position at money play.
- Features 2 & 3: the Score Map button for cube & move decisions, which show a 
color-coded map of all the cube decisions or best moves at different scores.

We have tested the features for bugs a fair bit already, and will be continuing 
to do so over the next few weeks.

Enjoy!
